Scaling Analysis of Solidification of Liquid Aluminum Alloy Flowing on Cooling Slope

Numerical study of solidification of A356 aluminum alloy flowing on an oblique plate with experimental validation

“…For cooling at the bottom of the plate, a convective boundary condition in the form of heat flux is given to simulate partial solidification of the melt due to heat transfer. A356 aluminum alloy is considered in computation, whose thermo-physical properties, together with additional system parameters, are presented in Table 1 [14]. The variation of slurry viscosity as a function of solid fraction is considered by a variable viscosity model.…”

“…The effect of mechanical vibration of metal mould on the production of thixotropic feedstock of A356 aluminum alloy has also been investigated [12]. In addition, numerical studies and scaling analysis along with experimental investigations of solidification of A356 aluminum alloy melt have also been reported [13][14][15]. Furthermore, both numerical and analytical studies on heat transfer and fluid flow behaviors of nanofluid with convective boundary conditions have also been reported [16,17].…”

Effect of Cooling Slope Angle on Microstructure of Al-7Si Alloy

“…From the above equations, it can be easily concluded that the boundary layer thickness decreases with increase in cooling slope angle for both laminar and turbulent flow. Although shear stress has greater impact at higher angles [19], its effect lasts for short period of time leading to less dendritic arm fragmentation and consequently resulting in coarse grains. Also, the overall heat transfer is less because of low residence time.…”

CFD Modeling on Influence of Impinging Spout Strength for Device Cooling with Water-Al2O3 Nanofluid

“…Additionally, the nanofluid thermal control is candidly spirited as ambient thermal control is poor to deliver the drive. Numerical and experimental reviews on heat spreading over rectangular domain are existent in texts [1][2][3][4][5][6][7]. Computational and experimental work with solidification are also illustrated [8][9][10][11][12][13][14][15][16][17][18][19][20].…”
